Eclipse Set up

Okay so just yesterday I think I finished setting up eclipse. At first when I was getting the android SDK I saw they had a bundle which included eclipse so I got that. I thought it would make the process slightly faster but I must have screwed something up on the way because I later noticed my R.java file wasn't generating(you may remember this is the file that is supposed to auto generate and it's used for linking the xml and java code). Anyway, I tried multiple solutions including the ones seen here and here at stack overflow. One problem I noticed was that I was missing some packages like the Android SDK build tools so I installed that but it didn't fix the problem although it may fixed part of it. Then I focused on the project build target because I had tried everything else so I thought maybe I had a different version of android SDK when the program was targeting a different version although I don't see why it would be doing this. I'm really not sure if I was on the right track or not but I kept getting errors such as saying things like my style is not supported, so I would fix this and then I would get an error saying my theme wasn't supported and I would fix that, etc. At this point I just decided to reinstall eclipse and be careful to try and install only what was needed and currently my R.java file has generated and I hope it stays that way.
